I have cheng shins in a classic tread pattern: ribbed front and block pattern rear on my CB350F.
Many people rip on these tires here because they are cheap (also inexpensive!)

and the rubber is supposedly not up to standards of the big european manufacturers.
I think the rubber compound is pretty hard to begin with, designed for long wear on really abrasive roads.
I have had them 3 seasons, but only put about 2500+ miles on them. There is tons of tread left and no cracking at all.
I readily admit they are NOT the same as high performance tires in terms of grip and wet road handling. However, they are smooth and stable at highway speeds and I have scraped the centerstand on a few lefthanders. I haven't experienced any "squirrely" tire behavior, but also haven't ridden on Metzelers or Dunlops of Bridgestones yet...
Therefore, I have nothing to compare them with. But for city riding, riverside cruising, and the occassional 100+ mile daytrip, they have been just fine for the small displacement bike.
Hope that helps and good luck on the employment front. savings dry up fast, especially if you spend them on hobbies.
